A mediation application is an enterprise application (EAR file)
that contains a mediation handler enterprise bean project. Installing the
EAR file into
WebSphere® Application Server (base) makes
the mediation handler available for use at a destination.
You must install the EAR file on every server on which you intend the mediation
to run, taking into account the following:
- If you intend the mediation to mediate a topic, you must install the mediation
on every server that has a messaging engine.
- If you add a new member to the bus after you have mediated a topic, you
must install the mediation on the new bus member.
- If you are installing on a queue, you must install the EAR file on the
queue point. For a partitioned
queue, you must install the EAR file on the cluster.
Installing a mediation application on a secure server
If
you are installing a mediation application for use when
WebSphere Application Server security
is enabled, you must ensure that the messaging engine can access the mediation.

the message engine can access mediations.
